  • Patent number: 9371801
    Abstract: In a two-pulse rocket motor provided with a pressure vessel, a first propellant placed within the pressure vessel that burns during a first pulse stage, a second propellant placed within the pressure vessel that burns during a second pulse stage following the first pulse stage, and a barrier membrane placed so as to cover the entire initial burning surface of the second propellant, wherein the barrier membrane is provided with an inner barrier membrane that covers the inner peripheral surface of the second propellant and an aft barrier membrane that covers the rear surface of the second propellant, and an end portion where the aft barrier membrane and the inner barrier membrane meet is joined over the entire circumference thereof. The ignition device includes an energy supply unit, an energy transfer unit connected at one end to the energy supply unit, and an ignition unit.
    Type: Grant

  • Patent number: 7997199
    Abstract: A workpiece 70 is set to holding rotating means and then liquid-state photosensitive resin 10 is supplied to a resin applying smoothing unit 150 to mold the workpiece 70 into a uniform thickness while rotating the workpiece 70 and applying the liquid-state photosensitive resin 10 to the outer periphery of the workpiece 70 by the resin applying smoothing unit 150. Moreover, while rotating the workpiece 70, liquid-state photosensitive resin, it is exposed by high-intensity ultraviolet light 30 and thereby, the surface of the photo-cured photosensitive resin is shaped to remove an unnecessary resin layer. Then, laser carving is performed by an infrared laser beam 40 to perform post-treatment.
